2. Heating

Note:

a.UP:

If move from Lo, the fan speed will be shifted to Maximum 1520 rpm.

If move from Maximum, the fan speed no change.

In up zone, 10 rpm is added for every 10s until Maximum 1520 rpm.

b.DOWN:

The fan speed will be decreased one step every 10 sec. until Minimum 1270 rpm.

c.Current Output Fixed:

Maintain at present fan speed.

d.Instantaneous Maximum:

Fan speed will be increased to maximum auto fan speed.

e.Temperature in ( ) is for Powerful Mode operation.

C. Fan Motor Control

1.Motor specification

High voltage PWM Motor

2.Feedback Control

a.Number-of-rotations feedback

Immediately after the fan started, rpm is checked and duty is added, and feedback control is performed. For high voltage PWM motor, it is done once every 0.5 second.

b.Offset duty T max/min limit

High voltage PWM motor has maximum offset duty. (Refer Indoor fan motor control basic rotation speed)

3.Abnormal Detection Control Conditions:

a.Out of rhythm signal input

b.If feedback number of rotations exceeded #2550 r/min or when less than #50 r/min.

Control: Fans stop

Return: Restart after 5 seconds

* It will not detect the out of rhythm condition within 5s for phase control motor (PWM motor is when duty=0) after start.

A fan stops when condition (1) and (2) happen within 25.0 seconds after fan starting, and if this happens for continuously 7 times, it will not retry.

FM lock processing

4.Restart Prohibition Control

Restart is prohibited within 5s for phase control motor (PWM motor is when duty=0) after fan stop (except re-ON the power supply).
